Clinical effect of artificial dermis in the repair of scar contracture in children with limbs burn

Objective:To explore the clinical effects of artificial dermis stent implantation combined with autologous split-thickness skin graft in repairing the scar contracture in children with limbs burn.Methods:Twenty-eight children with scar contracture after burn were divided into the observation group and control group according to the treatment method(14 cases each group).The observation group was treated with artificial dermis combined with autologous split-thickness skin graft after scar excision,and the control group were treated with thickness skin graft after scar release.The healing time of donor skin area,survival rate of skin graft,wound infection rate after 1 week of operation,and scar hyperplasia in donor skin area and skin graft area between two groups were compared.Results:The healing time of donor skin area in observation group was significantly shorter than that in control group(P<0.01).No infection in two groups was found after 1 week and 2 weeks of operation,and all skin grafts were survival.The difference of the VSS score between two groups after 6 months of following up was not statistically significant(P>0.05),and the score of skin graft area in observation group was better than that in control group(P<0.01).Conclusions:The clinical effect of artificial dermis stent implantation combined with autologous split-thickness skin graft in repairing the scar contracture in children with limbs burn is good,which is worthy of promotion.
